Hypercapnia, also known as hypercarbia, is a condition that occurs when a person has too much carbon dioxide CO 2 in their bloodstream. It can cause dizziness, fatigue, and shortness of breath. In mild hypercapnia, the body can often regulate itself, temporarily altering breathing by gasping or taking deeper breaths. Chronic cases, however, usually require medical intervention. Consistently increased levels of CO 2 in the bloodstream can be harmful over time, increasing the pH of your blood and affecting the health of the lungs, respiratory system , and other major systems in the body. Symptoms of hypercapnia can vary in severity and depend on the underlying issue. The symptoms of severe hypercapnia can be life threatening and require immediate medical attention.

Hypercapnia, also called hypercarbia, arises from having too much carbon dioxide in the blood. It typically happens with hypoxia, which is when there is not enough oxygen in the body. Hypercapnia happens when breathing problems make it difficult to take in oxygen and breathe out carbon dioxide. It is typically due to a disease that affects the lungs. Symptoms can range from mild to severe, and can include fatigue , headache , and confusion. Possible causes include the respiratory conditions chronic obstructive pulmonary disease COPD and asthma. Symptoms can be acute, meaning they start suddenly and last a short while. Or they can be chronic, meaning they last a long time. People with chronic hypercapnia may also experience a temporary worsening of symptoms. A person with hypercapnia might notice :.

Additionally, it has potent vascular and immunological effects [ 1415 ], hypercapnic.

Hypercapnia is the increase in partial pressure of carbon dioxide PaCO 2 above 45 mm Hg. Carbon dioxide is a metabolic product of the many cellular processes within the body, and there are several physiological mechanisms that the body has to moderate carbon dioxide levels.

The relevant physiology of ventilatory control, mechanisms, causes, and effects of hypercapnia are presented in this topic review.

Hypercapnic

Having too much carbon dioxide in the blood can cause serious symptoms. High carbon dioxide CO2 levels in the blood hypercapnia can be a life-threatening health crisis. It occurs when CO2 builds up in the bloodstream. This can be due to either an overproduction of CO2 or an inability to efficiently clear it from the body. Hypercapnia can occur from an infection, illness, or trauma.
